In this abstract, we present an approach for rapid mapping of the whole body B1 field at 3 Tesla. We use a combination of dual interleaved TR B1 mapping with continuously moving table imaging to measure the B1 field in the whole body in 90 seconds. Considerable variation is observed in the B1 distribution in different sections of the body. This measurement will serve as the basis for dynamic B1 field shimming with the moving table for whole body imaging in future work.
